Sistema satelital y metodo para latitudes circumpolares que sirve para monitoreo del tiempo y del clima, donde el sistema comprende una constelacion de dos satelites que en conjunto proporcionan una cobertura de 20° de elevacion o mas a traves de un area geografica de servicio sobre 60° de latitud, cada satelite tiene una inclinacion orbital entre 70° y 90°y excentricidad de entre 0.275 y 0.45, y una estacion base para transmitir y recibir señales desde dicha constelacion de dos satelites.

摘要

The present invention relates to satellite systems and more particularly, to the provision of a satellite system for weather and climate monitoring, communications applications, and scientific research at higher latitudes, referred to as the circumpolar region and defined here as the area with latitudes greater than 60°, in either the northern hemisphere or the southern hemisphere. Contrary to the teachings in the art it has been discovered that a satellite system and method may be provided using satellites in 24 sidereal hour orbits (geosynchronous) with inclinations (70° to 90°), orbital planes, right ascensions and eccentricities (0.275-0.45) chosen to optimize coverage of a particular service area located at high latitudes. A constellation of two satellites can provide continuous coverage of the circumpolar region. The satellites in this orbit avoid most of the Van Allen Belts.
